SPECIFIGATION forming pert of Letters Patent N0. 260,225, deted June 27, 1882. Applicntion filed February 8, 1882. (N0 n1o1lel.)

I0 all whom it mag; oonce1n Be in known thet 1, DOLPIIO H. ODELL, e oitizen of the Unitod Stetes, residing et the city of Deycon, in the county of Montgomery end Stete of Ohio, heve invented eertein new end useful Improvements in Roller-Mills, of which the following is e speoifioetion.

-This invention reletes to improvements in the meohenism en1ployecl to drive the rollers in roller grinding-mills; end the objeets o1 the invention ere to drive the rollers by meens of pulleys mounted 011 the1n et one side 01 the n1eehine only, end to provide simple end efficient meens for reguleting the strein of the driving-belts, ell in such menner thet free eceess oen be hed 10 one sicle of the mechine without denger of being oeught in ehe belts,

end e series of mills cen be sei: so thet the belts 1ney be 011 the inner sides of-the maehines with e free speoe upon their outside end the in the combination, in e clouble roher mill, of

driving belts end pulleys, e supporting-freme, an edjusteble freme, end meehenism f0r edjusting the letter so regulete tl1e streinof the driving-belts. The invention is olearly illustrated in the eeeompanying drewings, in which Figure l represents the driving belts end pulleys es errengecl 011 oneside of the meohine; Fig.2, the belt-tightener pulleys set edjnstebly 011 e frame. Fig. 3 is e front. elevetion of the mein driving p11lley end sheft. Fig. 4 is e front elevetion of the pulleys 011 one setzof rolls.

Fig. 5 is e horizont'el seocion 011 the line 00 x of double roller 111111. The freme of the meohine end the roller-shefts ere 11013 shown in t-he drewings. 'll1ey mey be oonstructecl in euy well-known wey.

F represents Ehe floor 011 whieh the freme of the rneohine usuelly elende.

y G G represent the pulleys upon the slowerspeeded rollers.

H H represent 1he speeded rollers.

I represents Ehe mein driving-pulley for transn1itting tne power t0 ehe meohine.

K represents the tigl1tener-pulley freme. It is shown 111 Figs. 1 end 2 es restziug upon the floor end ebutting egeinst tl1e mechine 01311- trelly between tl1e two sets 01' rolls. lt mey, however, be etteohed to 01 mede e pert of the freme of the meohine.

lt represenbthe sides of the tightener-frame.

M represents e sliding freme, hevingvertioel ribs errenged in grooves in nl1e immer feees of the stenderds Z Z. (See Fig. 5.) pon tl1e lower encl of the stendercl M ere c11t e series of reok-teeth, N.

V N represents e sheft journeled in the freme K, et; one side thereof, so thet pinions n, mounted on'seid sheft, will mesh with the reckt'eeth N.

0 represents e heud-wheel for revohiing seid sl1e1't to reise 01 lower the edjuseble pulley-freme M.

l? represeuts e tightener end power drivingpulley for the slower-speed rollers, mounted upon e sheft journelecl 011 seid freme M.

Q; represents e tightener-pulley mounted 011 the seme sl1eft es pulley P, end it is used to tighten the belt 011 tl1e fester-speeded rollers.

R represents e tightener-pulley of the slowerspeecled. rollers, mounted 011 shefb R, whieh sheft is journaled to Ihe sliding freme M.

If desirecl, the sheft R encl its tightener-pulley mey be etteehed edjustebly on the freme M,

111llevs 11.1011 the i'ester- 00 1 so thet 111 cen be reisecl encl lowered to regulete the strein of the belb of the slower-speeded rollers inclependent of the frerne M.

S represents e pewl ettaohedto the frerneK, whioh engeges the retoheb-teeth s 011 sheft N to loek or hold the freme'N to eny point of edjustment.

Power is trensmitted fron1 the mein drivingpulley I es follows: Belt T passes from pulley IOO I around tlxe pulley II, thence around the Lightenerqmlley Q, thence ar0und the 10Herpul ley II thence back again around l1e driving-pulley I. 'lhe slower-speeded rollers nre fiktiven bybeltUand the power is transmitted fr0m the pulley 1* 011 the shafb of tightener-pul ]ey Q, halt: U passing; from pulley l around pulley G, thence m0und the tightoner-pulley R,thence m*oundtheroller-pulleyG3,and back aguin monnd power-pnlley P.

lt will be seen that the n1achine 02m be instantlystopped 01 sta1ted byturuiug the hundwheel O am! looseniug 01 tighteniug tl1e belts, as the case may be, aud 1's u very important i'eature in the ommtion 0f roller-mills.

A modification 0f the arrangement; 0f T110 tightener-pnlleys might be mach: bylmvingthe pulley R mounted 011 an :1xis attached to the main fran1e 0f the machine, und mzule verlically ad justable us a belttightener siun fly.

\Vhat I claim is 1. In a roller-mill, the bcltdriving mechanism consisting in the combination 0[ tho belts T und U, the driving and roller pulleys, an l tightener-pullcys Q und R, armuged upon one side of the fmme 0f the machine, substantially as described.

2. In a double roller mil],thecombinationof driving 'belts und pulleys, the tightener-pulleys Q and R, and an adjustablefrzune adapted -haud in the presence 0f two subscribing witnasses.
